Main Story

In a spaceship floating somewhere near Earth, faceless aliens are spying on Rebecca Miyamoto, a half-American, half-Japanese genius who has been hired to teach at a Japanese school.

The class finds out that their newest teacher is a child genius who graduated from MIT at the age of 11. Some of the main characters get introduced, including a smart Chinese girl, a loud ditz with an ahoge ("cowlick" in the English version), hard-worker with a shiny forehead, normal girl with a minimal impact, and a strange girl whose face is drawn differently from the rest of the cast. The students decide to call their new teacher "Becky" and tease her a lot. Becky turns out to still have childlike tendencies and doesn't take the nickname too well, hiding behind a nearby curtain when she gets too embarrassed.
